Be it known that l, \Ynmmu Henson Sonnw, a suhjeet of the King of Great. llritain and lrelaiul, Works, h ewcastle-upon lIyne,

eonipressed air for operating; a motor or the like. In such plant it known to increase the energy of the compressed air by burn in therein a liquid fuel.

The present. invention has particular reference to the means used .t'or feeding the fuel to the combustion chamber, and it so desired water or the like vaporizable liquid into the combustion products for the purpose of reducing the temperature of the same, and at. the same time adding to the quantity of working tluid led to the engine.

The objectof' the. present invention is to improve and .u'ipli't'y apparatus of this kind so as to give a simple and automatic adjustment of the fuel, "after or like feed in accordance with the density of the air flowing through the combustion chamber or the like and proportional to the quantity or rate of {low of such air.

The present invention consists in means for increasing the energy of stored compressed air comprising means for feeding "fuel, water or the like into the compressed air, said means kinetic energy of the being dependent on the air in the pipe leadin from the reservoir to the engine.

The means used for feeding comprise a in the path of the air 'llowine' to the engine either a. direct or reverse l rtot action may be employed as in either case the feeding action will be dependent on the kinetic energy of the air stream that is dependent on the square of the velocity oi tiow and on the density. Instead of or in. addition i to the lhtot. tube an ordi nary injector action may be employed.

Referring now to the accompanying die..- grannnatic drawings which show convenient constructions of this invention such as may be applied to the air heating; devices used in automobile torpedoes; Figures 1 to 5 illns- Specification of "Letters Patent.

residing at lllswick, both liquid fuel and t t t into diagrammatically means for feeding liquid fuel. only into the combustion chamber; Figs. 6 and 7 show means for feeding Water ort-lie like into the air and combustion products respeo tirely.

According to Fi 1, liquid fuel from a tank, (1.,is led by a pipe, I), to a. nozzle, 0, within the air conduit pipe, f. The nozzle, 0, points in the direction of flow of the air and into an open cone piece,d. A pipe, 6, leads from the combustion chamber, g, Which is conveniently anenlargement of the air conduit pipe to the upper end of the :tuel tank, a. The air passing through the pipe,

, the kinetic energy of the moving stream.

In Fig. .2 instead of employing an cone, (7, a. litot tube, 71,, is emploved to set to taco the stream of air passing into the combustion ehai'nber, y. In this way, as is well. known, a greater pressure than that in the pipe, f, is transmitted. to the fuel tank, a, and the ditlerence oi? the pressures in the pipe, j, and tank, a, in this term is dependent on the, kinetic energy of the stream. In many cases itv may be found desirable to place some resistance such as a perforated plate, j, in the pipe, f, between the Pitot tube, h, and the combustion chamber, 9, as the Pitot pressure difierence may not; be sutiicient to etlect. satisfactorily the feeding. This resistance may however be of any convenient form and in fact the pipe leading to the combustion chamber may be arranged to itself other a sufficient resistance for the purpose required. The fuel in the term shown. in Fig. 3 is led to a spraying nozzle in the combustion chamber.

in Fig. 3 the Pitot tube action. is employed for collecting the air pressure on the liquid fuel while a reverse Pitot tube is employed for spraying. In this way the Pitot action is increased additional resistance may be required.

In Fig. 4.- a Pitot tube is employed for collooting, the pressure on the top of the liqui fuel and also for collecting air of slightly higher pressure than that. the combustion to the combustion chamber, g, exertsa and in some cases no In Fig. 5 instead of taking the spraying air from the Pitot tube, there is provided a cone, m, which collects the air and helps the oil to spray from the nozzle, 6.

n Fig. 6 the form of fuel feed illustrated in Fig. 3 is employed and in addition to the fuel tank there is provided a reservoir, n, for water, a solution of ammonia, salts or the like. The tank, a, is connected by a pipe, 0, to a litot tube, p, and by a pipe, to a nozzle, 1-, in the combustion chamber, whereby water or the like is sprayed into the products of combustion which not only has the eti'ect of cooling these down to a workable point but also adds to the volume oi. working fluid passed to the engine. In torpedoes where space is somewhat; limited this is a point of considerable importance.

In Fig. 7 instead ot'leading the water or the like from the tank, 11, directly into the combustion products it is first led through a spiral, s, placed conveniently in an enlarged portion, A, of the pipe leading from the combustion chamber to the engine. The water or the like is heated while passing through the spiral and is discharged into the combustion products as indicated at Z, in the form of a vapor or hot liquid.

The. l'eeding oi water or the like may oi course be aided by means ot a resistance in the path ot the main air stream as in the case oi feeding l'uel.

It will be evident that there are many equivalent ways of directly using the kinetic energy ot' the stream tlowing to the engine to feed the liquid fuel water or the'like into the air or combustion products.

Having now described my invention, what I claim as new and desire to secure by Letters latent is 1. Means for incrcasingthc energy of stored compressed air comprising in combi nation a combustion chamber, a conduit leading compressed air to said combustion chamber, a receptacle for liquid, means leading from said receptacle to said combustion chamber and means connecting said receptacle with the compressed air conduit, said means having an opening in the conduit facing toward the oncoming air whereby the kinetic energy of the air stream in the conduit produces a pressure in the liquid receptacle in excess of that in the air conduit and combustion chamber.

2. Means for increasing the energy of stored compressed air, comprising in combination a, combustion chamber, a receptacle for liquid fuel, a jet in said combustion chamber, a pipe leading from-said receptacle to said jet, a litot tube placed in a passage in which a current of air is flowing, and a pipe leading from said receptacle to the bottom of said end or said chamber remote from said ansaid Pitot'tube, as and for the purpose de scribed.

3. Means for increasing the energy of stored compressed air comprising in combination a combustion chamber, a passage through which airor gases are flowing, awater receptacle, a pipe connecting between water receptacle and the passage, a Pitot tube in said passage and a connection from said litot tube to said water receptacle, as and for the purposes described.
